#Prurigo.#

#Define prurigo.#

Prurigo is a chronic, inflammatory disease, characterized by discrete,
pin-head- to small pea-sized, solid, firmly-seated, slightly raised,
pale-red papules, accompanied by itching and more or less general
thickening of the affected skin.

#Describe the symptoms and course of prurigo.#

The disease first appears upon the tibial regions, and its earliest
manifestation may be urticarial, but there soon develop the
characteristic small, millet-seed-sized, or larger, firm elevations,
which may be of the natural color of the skin or of a pinkish tinge. The
lesions, whilst discrete, are in great numbers, and closely crowded. The
overlying skin is dry, rough and harsh; itching is intense, and, as a
result of the scratching, excoriations and blood crusts are commonly
present. In consequence of the irritation, the inguinal glands are
enlarged. Sooner or later the integument becomes considerably thickened,
hard and rough. Eczematous symptoms may be superadded. In severe cases
the entire extensor surfaces of the legs and arms, and in some instances
the trunk also, are invaded. It is worse in the winter season.

#What is known in regard to etiology and pathology?#

It is a disease of the ill-fed and neglected, usually developing in
early childhood, and persisting throughout life. It is extremely rare,
even in its milder types, in this country. Clinically and pathologically
it bears some resemblance to papular eczema.

#Give the prognosis and treatment of prurigo.#

The disease, in its severer types is, as a rule, incurable, but much can
be done to alleviate the condition. Good, nourishing food, pure air and
exercise are of importance. Tonics and cod-liver oil are usually
beneficial. The local management is similar to that employed in chron
